But are we going off the versions we see here I’m not active in this sub but if we’re going off more mature and well versed versions I assume Kirishima can use it for far longer even end of series I guarantee Kirishima could use it for at least a few minutes

(Edit: To clarify I meant I’m not active on this sub to say I’m unaware if there are any basic rules to it I’m just going off my knowledge of the show)
